Drill Bit GRAPHITE Hex shank 10.0 mm for metal, model 54T718

GRAPHITE twist drill bit model 54T718 is designed for drilling metal with a 10.0 mm cutting diameter and a hexagonal shank for reliable engagement in chucks and bit holders. The 10.0 mm working diameter provides a balance between hole size and material removal rate, making this drill bit suitable for common metalworking tasks. The hex shank allows quick insertion and prevents slipping during use with hand drills and drivers that accept hex shanks.

Advantages

The solid geometry and ground cutting edges deliver accurate holes and consistent performance in sheet metal and thin-walled components. The hex shank reduces rotational slip in the chuck or bit-holder, improving control when drilling with portable power tools. The drill bit’s material and heat-treated finish are selected to withstand the higher cutting loads and temperatures encountered when penetrating metal.

Suitable for

• Drilling holes in sheet metal and thin steel plates
• General metal fabrication and workshop repairs
• Use with hand drills and impact drivers that accept hex shanks
• Pilot and clearance holes for fasteners in metal structures

Key specifications

• Cutting diameter: 10.0 mm
• Shank type: hexagonal shank for secure engagement
• Intended material: metal (suitable for thin-walled and sheet metals)
• Tool compatibility: hand drills and drivers with hex-shank acceptance

How to use

Secure the hex shank in the drill’s chuck or bit-holder until it is fully seated to prevent wobble. Mark and center-punch the drilling location on the metal surface to reduce walking. Use an appropriate drill speed for metal and apply steady, moderate pressure; avoid excessive feed that could overheat or dull the tip. For thicker or harder metals, use a lubricant or cutting fluid to reduce friction and extend tool life. Retract the bit periodically to clear chips when drilling deeper holes.

Usage recommendations

Always wear appropriate eye and hand protection when drilling metal. Match drill speed and cutting fluid to the metal type and thickness to achieve optimal hole quality and drill life.
